Specification of Letters Patent.

Patented Aug. 18, 1914.

Application filed September 5, 1913. Serial No. 788,327.

To all whom it may concern Be it known that I, ALFRED P. HAUs'rE'r- TER, a citizen of the United States, and a resident of Norwood, Hamilton county, State of Ohio, have invented certain Improvements in Planers; and I do declare the following to be a clear, full, and exact description of the invention, attention being called to the drawing which accompanies this application and forms a part thereof.

This invention concerns machine-tools of the pl aner-type and relates to improvements whereby convex surfaces may be planed.

The invention consists of the construction of these improvements as hereinafter de scribed and claimed, and as illustrated in the accompanying drawing, in which Figure 1, shows part of a front view of a planer with the features of my invention applied. Fig. 2, is a side view of this figure. Fig. 3, is a vertical cross-section, taken on line 3--3 of Fig. 1.

In the drawing, A, indicates a piece of work, having a partly cylindrical surface, which is to be planed and finished. It is supported upon the planer-table B, to which it is secured in the usual manner. This table has a reciprocating motion upon the bed 7), whereby, upon movement in one direction, the planer tool C, is caused to act in the usual way. The tool is transversely as well as vertically adjustable, to meet the position of the work on the table. A planer-head whereby the tool is carried, serves to obtain the transverse adjustment, a screw (Z, being used for the purpose. The vertical adjustment is effected by a rail D, in which the screw is mounted and which rail is supported on two housings E, E, on which it is vertically adjustable. The planer-head, except as hereinafter described, is of customary construction.

7 is the tool-holder, to which the tool C, is held by clamps 8. The tool-holder is hingedly connected and carried by a slide 9, adjustable by means of a handle 10, the object of this adjustment being to set the tool closely to the work, more particularly for the purpose of determining the depth of the cut to be removed. The tool-holder and slide may also have the customary swivel adjustments in a plane parallel to the face of the rail, the object of these adjustments being to set the tool so that, as to its cutting motion, it may be inclined to the work at any desirable angle. Screws 11 and 12 respectively, serve to hold these adjustments. The planer-head considered in its broadest scope as to its function for holding the tool and irrespective of any details of its construction, whether they be of the kind described or of any other type and for which no novelty is claimed, is supported to move upon certain means to be presently described whereby it is guided to lead the tool while it is on its feed-motion.

If the planer-head is to have the aforesaid swivel-ad ustment, then an intermediate carrier-plate 13, is provided which moves upon these guiding means. These means are so arranged as to cause the tool, the same having previously been properly set to the work, to be fed over the work on a convex arc of a circle. They consist of ways 14, provided on the face of a segmental plate F, which ways follow the arc of a circle. The carrier-plate is fitted to these ways, they being preferably grooves, by suitable means, as for instance by lugs 15, which project rear-wardly from carrier-plate 13, and are closely fitted into said grooves. Means are provided to hold this plate on the guideplate with its lugs in their ways, for which purpose the grooves forming the ways are under-cut to receive the heads of clamping screws 16.

A rack 17 or equivalent machine element, concentric with ways 1 is provided on guide-plate F, preferably on its outer edge, and a complementary machine element, a pinion 18, in this case, is mounted on carrier-plate 13. A hand wheel 22 is provided for its rotation. It will now be seen that if the pinion is rotated, the planer-head with the tool-holder will be caused to move in a path which is parallel to, and concentric with a convex surface to be produced on the work, and the cutting edge of the tool is fed forward correspondingly.

Guide-plate F, is rigidly connected to a saddle 19, which is fitted to ride on rail D. This saddle which carries the entire structure, including the planer-head, may be ad justed on said rail by means of screw (Z, as before mentioned. Plate F, being wider than the saddle, is backed up by the rail, by means of rearward extensions 21, which are fitted to the rail so as to slide thereon.

General planer-work on fiat surfaces may also be done in which case carrier plate 13 is not moved and may be rigidly locked to guide-plate F by means of bolts 16. F or feed-motion in this case, the saddle is moved on the rail. If the surfaces to be planed are at an angle to the planer-bed, feed is by moving slide 9 by handle 10, the slide being adjusted to proper angle on the carrier by means of bolts 12 Which hold it thereto. These bolts are seated in a groove 23. To prevent interference With this adjustment of the slide by handwheel :22, this latter may be detachably seated.

Having described my invention, I claim as new:

1. A machine-tool of the planer-type, comprising a reciprocatory Worlasupport, a rail, a saddle adjustably fitted thereto, a guideplate superposed upon the front side of the saddle and rigidly attached thereto, it eX- tending also beyond said saddle on each side Where at its rear side it is fitted into sliding engagement With the rail, concentric Ways provided on the face-side of said guide-plate, a carrier-plate niovably fitted to the Ways of the guide-plate, means to move the carrier-plate on the guide-plate so as to follow the Ways thereon, and means to hold a tool provided on the carrier-plate.

2. A machine-tool of the planer-type,co1nprising a reciprocatory Work-support, a rail, a saddle adjustably fitted thereto, a guideplate having concentric grooves in its frontside superposed. upon the front side of the saddle and rigidly connected thereto, a carrier-plate having lugs on its rear-side Which are movably fitted into the grooves mentioned, means to hold these lugs in these grooves, a planer-head provided with adjustable tool-holding means secured to the carrier-plate, and mechanism to move the carrierplate With the planerhead on the guide-plate so as to cause the carrier-plate to follow the groovestherein.

In testimony whereof, I hereunto my signature in. the presence of two Witnesses.
